I sold some content through a few freelance sites where you could write whatever you wanted and let it sit out there to be purchased and reused without attribution. (ConstantContent I think was the name of one of them). Downside to that is that it's impossible to build a name or a portfolio since you're not credited.

I also did some freelance work through Upwork, although that place is a fright and a total race to the bottom.

I had a somewhat steady gig writing under my own name on a small niche political blog. Problem was, the politics of the owners weren't the same as mine, and as much as they claimed to welcome all voices, I was pressured and edited towards their point of view.

I much prefer the format here. I write what I want, when I want, and sometimes I get a nice payout. All the while I am actually earning legitimate followers who faithfully show up to read and comment, and to me that is incredibly rewarding. Though I do have a 9-5 that supports me, so I can empathize with someone who is relying on their writing to feed their family.
